Primary Outcome Measures:
  • Change From Baseline in Mean Diurnal Intraocular Pressure (IOP) in the Study Eye at Week 4 [ Time Frame: Baseline, Week 4 ] [ Designated as safety issue: No ]
    Intraocular pressure (IOP) was measured in the study eye at baseline and Week 4. IOP is a measurement of the fluid pressure inside the eye. A negative number change from baseline indicates a reduction in IOP (improvement).
